1. Do you need support for Assetto Corsa Competizione? Please use the proper forum below and ALWAYS zip and attach the WHOLE "Logs" folder in your c:\users\*youruser*\AppData\Local\AC2\Saved. The "AppData" folder is hidden by default, check "Hidden items" in your Windows view properties. If you report a crash, ALWAYS zip and attach the WHOLE "Crashes" folder in the same directory. Do not post "I have the same issue" in an existing thread with a game crash, always open your own thread. Do not PM developers and staff members for personal troubleshooting and support.
  2. As part of our continuous maintenance and improvements to Assetto Corsa Competizione we will be releasing small updates on a regular basis during the esports season which might not go through the usual announcement process detailing the changes until a later version update where these changes will be listed retrospectively.
  3. If ACC doesn't start with an error or the executable is missing, please add your entire Steam directory to the exceptions in your antivirus software, run a Steam integrity check or reinstall the game altogether. Make sure you add the User/Documents/Assetto Corsa Competizione folder to your antivirus/Defender exceptions and exclude it from any file sharing app (GDrive, OneDrive or Dropbox)! The Corsair iCue software is also known to conflict with Input Device initialization, if the game does not start up and you have such devices, please try disabling the iCue software and try again. [file:unknown] [line: 95] secure crt: invalid error is a sign of antivirus interference, while [Pak chunk signing mismatch on chunk] indicates a corrupted installation that requires game file verification.
  4. When reporting an issue with saved games, please always zip and attach your entire User/Documents/Assetto Corsa Competizione/Savegame folder, along with the logs and the crash folder (when reporting related to a crash).

VSync vs AC FPS Cap vs Drivers Frame Rate Limiter

    As the title suggests, what's the best method to prevent stutters? I have tried Vsync and FPS cap from AC and both give me stuttering (mini freezes now and then). There is less stuttering with Vsync but there is added latency. Surprisingly, FPS cap doesn't give me tearing or at least I don't notice it.

    What about using the drivers fps limiter and remove AC FPS limiter? Will that help? I have a R9 Fury, 1050mhz, 500mhz.

    I totally don't care and just set vsync.
    There is some lag between what you see and the physics, but it doesn't really matter to me. FFB is realtime, the most important thing to react to.

    After 1.10 the only thing that works for me:
    - fps cap off
    - in game vsync off
    - Nvidia forced Advanced Vsync
    - max prerendered frames to 1 (optional to help with the lag)

    Reduce input lag. Can be used on all games.

    I find running the highest fps you can sustain consistently works the best. I run at 115fps capped in AC with very marginal stutter. Lots of moving parts when your talking about screen tearing so you will need to test settings yourself. Try to stay away from multiples of your screen refresh rate as that will make tearing more noticealble

    on \Steam\steamapps\common\assettocorsa\system\cfg\graphics.ini

    set MAXIMUM_FRAME_LATENCY=1

    Still can be set at driver level via nvidia inspector (now named nvidiaProfileInspector)

    Running with unlocked FPS and MAXIMUM FRAME LATENCY at 1 has helped a bit, stuttering happens less often now! I guess I'll have to invest in a Freesync monitor for a smooth experience.

    Thank you for all the help guys, appreciate it :D

    Hi! I have an R9 Fury just like you, and I'm also running an Asus MG279Q monitor, 1440p, IPS, 144hz, Freesync (standard range is 35-90hz but I modify mine to 44-120hz). I don't feel I need more than 60fps in Assetto Corsa so I use the ingame frame-rate limiter (which I find works the best out of the three options mentioned above) at 60fps, but with Freesync there's absolutely no tearing or stuttering whatsoever. It works really well in Assetto Corsa.
